Redemptive/historical preaching, as commended by many today, is like teaching lifeguards how to get swimmers off the bottom of the pool, but to be sure to behave thereafter as though getting them dry and breathing the air presents a constant temptation to moralism. It requires preachers to act as though the first three chapters of Ephesians had been written by the apostle Paul, with the last three chapters being contributed by Dale Carnagie. Gahk.
Also known inside my head as “Why is the Bible so thick if it only says one thing?”
